Introduction Hang En Cave Phong Nha – Ke Bang National Park
Hang En Cave is located in Phong Nha – Ke Bang National Park, Quang Binh, Vietnam. This is the third largest natural cave in the world, after Son Doong Cave (also in Phong Nha – Ke Bang) and a cave in Malaysia.
En Cave possesses a wild and majestic beauty, the cave entrance is relatively small but inside is a large, majestic space with many stalactites and stalagmites with unique shapes. A special feature is that there is an underground river flowing through the cave, creating a beautiful landscape. In addition, sunlight penetrates through the crevices into the cave, creating a shimmering, magical lighting effect. Besides, you can encounter many wild animals such as swallows, bats, insects, adding another layer of attraction to this remarkable natural wonder.
The fascinating formation of Hang En Cave

Hang En Cave is the result of millions of years of complex geological activity. The formation of this cave began with rainwater seeping into the ground, dissolving limestone to form a weak acid solution. This solution slowly erodes the limestone, creating small cracks. Over time, these cracks expand, forming caves.
In particular, the underground river flowing through En Cave has played an important role in creating unique shapes inside the cave. The fast-flowing water carries sand and gravel particles that hit the cave walls, abrading and creating strange shapes such as stalactites and stalagmites. Stalactites are formed from drops of water dripping from the cave ceiling, carrying minerals and depositing them. Stalagmites grow from the cave floor, the result of the deposition of minerals from drops of water dripping from the cave ceiling.
In addition, changes in sea levels also affect the formation of caves. When the sea level rises, water floods into the cave, dissolving and carrying away minerals, creating vast spaces. Conversely, when the sea level falls, minerals are deposited, creating thick layers of sediment. Over millions of years, under the influence of natural factors such as water, wind, and geological activities, Hang En has gradually formed the majestic beauty it has today. Each stalactite and stalagmite in the cave is a work of art created by the hands of nature.
